Narrative:

I relieved the previous controller as I looked at the flight progress strips. I had noticed a strip on a lifeguard aircraft that had no track in the sector, and was about 30 mins old. I assumed that the aircraft was handed off and shipped. I marked the strip accordingly and put it in the strip well.
